FLUID MOTOR OR METER.

SPECIFICATION forming part of Letters Patent No. 791,368, dated May 30, 1905.

Application filed August 31, 1903. Renewed November 2, 1904. Serial No. 231,068.

To all whom, t may concern.-

Be it known that I, WILLIE H. REYNOLDS, a

- citizen of the United States, residing at Austin, Chicago, in the county of Cook and State of Illinois, have invented new and useful Imimproved means for deriving from the passage of water through a device movement of parts actuated by the movement of the water substantially proportionate to the quantity of the latter, so that by such derived movement` power dependent upon the water pressure;

may be transmitted or the quantity of water passing may be measured, or both, as may be desired, the device in question'therefore being adapted to serve either as a meter or as a.

motor, according to the detail construction of rthe mechanism to which the movement is transmitted.

It consists in the features of construction of the mechanism for primarily converting the movement of the water into the movement of exteriorly-operating parts, as set out in the claims.

In the drawings, Figurel is a section made axially through the cylinder of the device constituting my invention. Fig. 2 is a transverse section at the line 2 2 on Fig. 1. Fig. 3 is an end View of the left-hand end of the motor. Fig. 4: is a detail view showing a modification of the means for operating the valves from the travel of the piston, the parts being represented as they would appear in a sectional view similar to Fig. 1.

In my invention a cylinder 1 is supported, preferably in horizontal position, and is closed at its opposite ends by heads 2 and 3 of sulo` stantiallyv similar construction, but different in a slight detail hereinafter pointed out. Each of the heads2 and 3 has two cavities or ducts 4 and 5, respectively, each duct having one end openinginto the cylinder and having at the other end, at the inner side of theheadthat is, the side toward the opposite headan opening4 in line with the corresponding opening of the opposite cavity of the opposite head, said openings in line being con.

nected by pipes 7 7, respectively, which for convenience in assembling the parts are each made in two pieces joined by couplings 8 8. The cavities 5 in each of the heads have, beside the opening to which the pipe 7 is connected, an opening in line therewith at the outer side of the head for connection one with a water'supply or inlet pipe 9 and the other with a service or outlet 10, and the openings connected with these pipes, respectively, may be named the inlet and outlet or supply and service openings. of the ductsl and 5 within the cylinder there are connected the tubular studs or posts 11 11 11 11, which are axially bored to afford continuous communication between the interior of the cylinder and the ducts 4: and 5, respectively. At the-portion of said studs or posts within the cylinder they are .provided at the outer side-that is, the side toward the cylinder-wall-with a seat for a 'valve 12, which has cylindrical heads or ends 12L lodged in aperturesbored transversely into said studs or posts 11 at points opposite the seats mentioned, respectively, so that said' cylindrical valve-heads may be thrust across the inlet-ducts, `which extend axially through the poststo reach the seats at the opposite side. These'seats are preferably formed in To the ends f plugs 13 13, which are screwed into the sides of the posts 11, and because it is desirable to vgain easy access to them for the purpose of y renewing the annular seating-gaskets or cushions 14, with which they are provided, the cylinder has apertures in line with said plugs, respectively, which are closed by plugs 15 15, which may be withdrawn to insert and remove the seat-plugs 13. The length of each valve 12 is such that when seated at one end it is withdrawn substantially from across the axial duct of the posts 11 at the other end, opening free passage through said posts for the water in or out, as the case may be. The cylindrical heads of these valves are not designed to seat Huid-tight where they are thrust through the sides of the tubular posts 11, but are only yiitted therein for the purpose of guidance,

their effective seating being obtained at the ends on the annular seating-gaskets 14 in the plugs 13. The heads of the valves 12 are hollow, being axially apertured from end to end.

A piston 16 plays within the cylinder 1 on an axially-situated rod or stem 17. This stem obtains guide-bearings at the centers of the heads 2 and 3, which have the eylindrically- `protruding bosses 18 and 19, respectively, in

' ing a plunger having at its inner end a stopnut 21, between which and the end of the bore made for the guide-bearing of the rod 17 there is coiled on the plunger a spring 22, tending to thrust the latterinward. At the outer end of the plunger it has a head 23, which stops against the outer end of the boss 18 and may serve as a means for actuating any suitable form of registering mechanism for recording the strokes of the piston which are communicated to the rod 17, as hereinafter explained,

thereby adapting the device to operate as a meter. It will be manifest that devices for transmitting power proportionate to the water-pressure operating on the piston may be substituted for the devices shown for merely registering the movement. On the rod 17 at opposite sides of the piston and at positions suitably near to the valves 12 12 to perform the functions hereinafter indicated there are secured collars or flanges 24 24, and coiled about the rod on the side of said eollars toward the piston are springs 25 25. Mounted on one of the posts 11 at each end there are latches 26 26, provided with springs 27 27, tending to hold them at their free ends inward toward the rod 17 and against the pieriphery of the collars 24. These latches have each a shoulder 28 in position to engage the eollar 24 and stop the longitudinal movement of the rod 17 in the direction in which it would be thrust by the movement of the piston encountering the spring 25. The end of the latch toward the piston is sloped on the side toward the rod 17 to operate as a cam upon the encounter therewith of the hub or central boss 29 of the piston when thelatter having first encountered the spring 25 has compressed said spring suficiently to enable the boss or hub to reach the sloping cam-face 30 of the latch, and by such encounter the latch is crowded outward from the rod and its shoulder 28 disengaged from the collar 24, whereupon the spring 25, which has been compressed while the hub 29 of the piston was approaching and acting upon the cam-face 30 of the latch, reacting thrusts the rod onward in the direction in which the piston has been moving to compress the spring. Means are provided by which the rod in its longitudinal movement under the thrust of the spring operates the valve 12 at one end for seating it toclose the duct in the post 11 connected with the inlet and the valve 12 at the other end to close the duct in the post 11 connected with the outlet and to open the ducts in the opposite posts connected, respectively, with the outlet and inlet. ln the principal figures l have shown this means comprising a bell-crank lever 31, fulcrumed on one of the posts 11, having one arm provided with a slot 32, which is engaged by a stud 33 on the valve, while the other arm has a slot 34, engaged by a stud 35 on the rod 17. In each case the stud is conveniently in the form of a screw set through the slot into the part to which it pertains-valve or rod, as the ease may be.

In the operation of the structure as thus far described, assuming the position of the parts at any starting-point as that shown in Fig. 1, the fluid will be entering through the inlet-passage 5 at the left-hand end and passing through the post 11 whose axial duct is open, forcing the piston 16 toward the righthand end, at which the axial duct is open through the post 11 connected with the outlet-pipe 10. As the piston moves under the pressure of the water and as water is drawn from the service system connected With the outlet its hub 29 at the right-hand side will encounter the cani-slope 30 of the latch 26 and will disengage the shoulder 28 from the collar 24 after the spring 25 has been sufficiently compressed to permit said hub to reach said cam-slope and traverse it far enough to effect such disengagement. The reaction of the spring will thereupon thrust the rod 17 toward the right-hand head, and the collar 24, operating upon the arm of the bell-crank lever having the slot 34, which is engaged with the rod, will by means of the other arm of the bell-crank lever, having the slot 32, thrust the valve 12 across the open duct in the post 11 leading to the outlet and seat it at the outer side thereof, closing said outlet and opening the duct through the post 11 at the other side, which is connected by the pipe 7 with the inlet 9. The samemovement of the rod 17 will by means of the stud 35, connecting the other bell-crank lever through the slot 34 in one arm, rock said lever about its fulcrum, causing the other arm having the slot 32, engaging the stud 33 of the opposite valve, thrust that valve across the duct in the post 11 leading from the inlet and seat it, closing said duct and opening the duet in the opposite post 11, which is connected, by the other pipe, 7, with the outlet 10. This change in positions of the valves will reverse the water connection, admitting it at the side of thc piston from which it was before the change being forced by the movement of the piston IOO ITO

and permitting it to escape from the side at which it was before admitted. The water entering through the inlet 9 and discharged through the outlet 10 will continue itsventrance and discharge by said passages, respectively, without interruption except for the unobservably short time occupied by the thrust of the rod under the action of the spring when released Afrom the latch, as described, and no observable interruption o f the iiow of the water will thereby `be caused and no change in the pressure incident to such flow except to the extent of the resistance which the spring -opposes to the and since the pressure of the water on thesey valves is nearly balanced the resistance Vof the spring to the movement of the piston may be so slight as to have no perceivable elect upon the flow of the water. This effect is further diminished by making the valves l2 12 hollow-that is, axially apertured from end to endso that the volume of water which they displace in moving across the current which is passing through the posts 11 is reducedto minimum and is permitted to pass through the valve itself during the movement of the latter until it reaches its seat.

It is not necessary to be limited to a lever connection between the rod 17 and thel valves 12 12. A cam connection between'said moving parts is easily provided, and such connection is shown is detail in Fig. 4. ln this movement of the rod in either directionmodification of the structure the rod 17 is expanded and slotted, forming at each end a blade 36 passing through the valves 12 12 between the heads, and these blades are prorod in moving in one direction will by the engagement of the oblique slots in the yoke carry the valves transversely to one end of their path and by the movement inthe opposite direction will thrust the valves back transversely to the other end, operating, therefore, with the same effect as the bell-crank levers above described. It will be understood that the camslots in the yokes at the opposite ends of. the cylinder are oppositely disposed, sothat the thrusts the valves at opposite ends in opposite vers, their arms which engage the valves extend from the respective fulcrums in opposite directions for such engagement.
